Application led February 28, 1916. Serial No. 80,930.

To all whom t may concern:

Be it known that I, WILLIAM J. DUNN, a subject of the King of Great Britain, residing at Montreal, in the Provinceof Quebec and Dominion of Canada, have invented certain new and useful Improvements in Edge-Staining Devices for Trimmed Wall- Paper, of which the following is a specification.

'The presentinvention relates'to a device or appliance for placing coloring matter of the same character as the background of Wall-paper to the side trimmed edges thereof.

One .object of the invention is t'o provide an appliance which will apply a' coloring matter to the side trimmed edge of Wallpaper as it is fed through a trimming and pasting machine.

A further object of the invention is to so construct such appliance that it Will. apply the coloring matter directly to the side edge of the paper, thus eliminating the White or of-color streak along said trimmedl edge, Which Wouldvotherwise appear when the p aper is placed upon the wall'. A

A further object of the invention is to provide a simple and compact appliance for -doing this work, and tot provide means for pressing the paper into constant contact with the coloring matter distributing member of such appliance.

A further object of the invention is to provide a flange or shoulder on the color applying member, which Vwill act to place.

the coloring matter along 'the trimmed side edge without applying it to the decorated surface of the paper, and also serve as a guide in the forward travel of the paper.

A further object of the invention is to so arrange and mount the appliance of the present invention as to enable itv to be adjusted to accommodate dierent widths of paper.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings: i

Fig. 5, a section on line 5-5 of Fig. 4,

looking in the direction of the arrows.

' The edge-staining or coloring device of the present invention is specifically adapted for use with that type of Wall-paper, trimming and pasting machines in which side trimmers are provided-for cuttingof the margin of the paper to leave the edges per'- fectly smooth and parallel, in order that when the paper is hung, the edges abut rather than overlap, this abutting of the edges -being in accordance with the most modern practice of hanging Wall-paper.

It has been found in practice that in trimming the marginal edge of Wall-paper, a white line or surface is lproduced along such trimmed edge, with the result that when the paper is hung, a division line is formed between each strip orl section of paper, by reason of the white or oft-color edges produced by the side. trimming operation coming together. This exposed line of contact disfigures the appearancev of the paper and tends to destroy the continuity of the design or pattern. It is therefore highly desirable that these white or of-color edges produced by the side trimming operation be of the same color and character as the body ofV the paper, thus producing, when the paper is placed upon the Wall, a continuing expanse ofv colored background and eliminating the White or olf-color division lines. Heretofore this tinting or coloring has been done by hand, which is a slow and tedious o eral tion, and not 1n every instance success as to the results sought. f

-The principal object, therefore, of the present invention is to apply the proper tint or color to the trimmed side edge of the paper by mechanical means and in a regular and uniform manner, and to carry on this operation simultaneously with the feeding of the-paper through the machine, entailing no further operations than are gone through inthe ordinary preparation 'of the paper l'for hanging by the use of such machines.

Although the present invention has been illustrated in connection with a certain type of Wall-paper pasting and trimming machine, it is to be understood that the particular mechanism shown and vdescribed is 'only for the purpose of showing one means of practising the invention; and the invention is not limited thereby except as some portions of the mechanism may be claimed broadly for the purpose of making` an operative combination.

Referring now to the drawings, and particularly to Figs. 1 and 2, the machine With which the present invention is shown as* employed, consists of side plates-6 joined together by suitable vtie rods 7; and'suspended from a rod 7 held in the side plates is a hanger 8 comprising arms 8a held in place by means of straps or links 9. These straps are removable to allori7 one or both of the arms 8a to be removed and permitthe mounting of fresh rolls of paper. This hanger serves to carry a roll of Wallpaper 10 which is mounted on a rod 10a. Mechanism for trimming the sides of said paper is shown, comprising a cutting disk 11, acting upon a backing roll 12, both disk and roll being provided with overlapping circular cutters. A tank 13 for a pasting medium is also carried by these side plates and is supported by suitable cross supports .14. Adapted to revolvepartially Within and partially Without this tank is a paste applying- Wheel or roller 15, mounted upon a shaft 16, 'which latter is suitably driven. A scraper 17 is provided for removing the surplus paste/ from the pasting roller 15, Which scraper is mounted upon a rocking crossshaft or bar 18. A feed roller 19 isprovided, With which coperates a pressure roller 20, carried by an arm 21, said pressure roller 20 serving to distribute and thin the paste evenly over the face of the paper to which it has been applied by tue roller 15. A. scraper 22 for each side edge of the paper is provided for removing any excess paste from the marginal edges of the paper, so that When the paper is hung, thispaste Will not be squeezed out and onto the outer surface of the paper.

The paper, after leaving the Scrapers 22,

- passes over a suy'iporting rod 23, thence over a roller 24, and between discharge rollers 25 and 26. After leaving` said discharge rollers, the paper passes across a. plate o 'r table 27, above vvhichis located a cross-cutter 28 actuated crosswise of the paper by a handle 29. The paper then passes onto an apron'30, which is supported bv a suitable support 31. Located above the roller 24 is a shiftable cutter 32, one for each side of the machine, for cutting oif sections from the paper of such width as may be desired. A guide or,

indicator mounted upon a standard or support 34 is provided, which is for the purpose of enabling the operator to 'determine at what point in the pattern each length of paper is tobe severed in order to have the pattern match properly.

All of the fregoing described parts are mechanism which go to make up a practical machine for trimming and pasting Wallpaper, is fully shown and described in my co-pending application, Serial vNo. 80,929, filed by me February 23, 1916, and entitled Machines for trimming and pasting Wall paper, but, as heretofore stated, the

precise mechanism shown and described is .75

of, is believed to benecessary in connection With the present invention.

The subject-matter of the present inven-` tion is illustrated in detail in Figs. 3, 4 and 5, and comprises a` receptacle 34 formed With a Well for the purpose of receiving a suitable stain or coloringsolution'. Extending from the lower end of the receptacle 35 is a lug 36 formed with a holev 37 extending therethrough. This hole receives a rod 38 secured to the plate 6; and the lug 36 is tapped, as at 40, to receive `a set screw 39 for locking the receptacle 34 to said Iod. By means of this arrangement, the receptacle can be adjusted back and forth on the rod 38, so as to properlyposition it With respect to the side edge of different Widths of paper.

Mounted Within the receptacle 34 is a roller 41, against the surface Vof Which operatesy a scraper 42; and this roller is formed with a shoulder 43, which provides a surface that Will contact the trimmed side edge of the paper and-apply color thereto, and which also serves as a guide for the paper 'as it is passing through. The roller is mounted to revolve upon a stem 44, and, as shown, is locked inplace by a locking member 45. As Will be seen, the roller revolves partially within and partially Without the Well 35 of the receptacle 34, and it is-this member which acts to apply the tinting or coloremployed. y

ing matter to the trimmed side edge of the r paper.

Referring now to Fig. 5, it Will be seen that when in operation, the paper extends across the surface of said roller and abuts against the shoulder 43. This shoulder tends to apply coloring matter directly to ,the trimmed side edge of the paper, which edge mounted upon a stem 47, Which. is carried by an arm 48 pivoted as at 49, and held under downward tension by means of the rin 5l, which 1s secured at one end 'by a hook be objectionable,

50 on the arm 48, and at the other end by a lug 52 on the side of the casing 34.

By referring now to Fig. A1, it will be seen that the color applying mechanism of the present invention is placed in advance of the side trimming cutters 11, soy that the coloring mattei is applied after the side trimming operation, as, of course, is essential, since it is the side trimming operationv that produces the objectionable White. or offcolor edge. It is also to be noted that the color applying mechanism is located rearward of the pasting appliance, so that the paste. is applied after the edge has been tinted or colored.

It will Ibe apparent from the foregoing description that, as the paper is fed through the machine, the trimming roilersll, one at each side of themachine, serve to trim both side edges thereof, and each edge of the paper is then subjected to the action of the roller 4l (there being a roller for each edge), whereby coloring matter is placed upon both of tbe trimmed edges, staining or coloring the edges the same color as the background of the paper. It is apparent that this Work is carried on continuously as the paper is fed through the machine, and that the paper does not have to be subjected to any further operations, save the usual operations of feedl ing the paper through the machine.

By applying the coloring or tinting matter in the manner set forth, such matter is applied only to the under face and side edge of thev paper, and is not'placed upon the decorated surface of the paper, which would in that it might vbecome smeared in the later operation of applying the paper to the wall. Although the mechanism has been described with considerable detail, the use of iother and equivalent means is contemplated, and, in fact, the invention is not limited other than may be set forth by the terms of the appended claims.
